Building Self-Reviewing Code Generation Loops for Web Extraction

Self-reviewing code generation for web extraction means letting an LLM write real extraction code, running that code against real page HTML, checking the output mechanically, and revising the code when verification fails. In this article, we’ll build that loop ourselves instead of treating generated code as correct by default. We’ll start with a simple web scraping test against books.toscrape.com , then make the setup harder with holdout pages, JavaScript-rendered content, and infinite scroll.
